Lub cev muaj zog ruaj kawg bearing
Taag kawg bearings siv radial bearings muaj peev xwm nqa tau ua ke (radial thiab axial) loads. Cov bearings muaj xws li: sib sib zog nqus groove pob bearings, ob kab los yog khub ib kab angular hu rau pob bearings, self-aligning pob bearings, kheej kheej cov menyuam bearings, matched tapered menyuam bearings, NUP hom cylindrical menyuam bearings los yog nrog HJ lub kaum sab xis NJ hom cylindrical cov menyuam bearings .
Rau kev xaiv ntawm qhov kawg ntawm lub cev muaj zog txhawb nqa (xa mus rau qhov kawg ntawm lub cev muaj zog), cov hauv qab no yuav tsum xav txog:
(1) Kev tswj xyuas qhov tseeb ntawm cov cuab yeej rub tawm;
(2) Qhov xwm txheej ntawm lub nra uas tau tsav los ntawm lub cev muaj zog;
(3) Cov kabmob lossis cov kabmob sib xyaw ua ke yuav tsum tuaj yeem tiv taus qee qhov axial quab yuam.
Ua ke cov saum toj no peb tsim cov ntsiab lus, nyob rau hauv me me thiab nruab nrab motors, sib sib zog nqus groove pob bearings yog feem ntau siv raws li thawj xaiv rau lub cev muaj zog taag kawg bearings.
Sib sib zog nqus groove pob bearings yog cov feem ntau siv dov bearings. Thaum siv qhov sib sib zog nqus groove pob bearings, cov qauv ntawm lub cev muaj zog txhawb nqa qhov system yooj yim heev, thiab kev saib xyuas kuj yooj yim. Sib sib zog nqus groove pob bearings feem ntau yog siv los dais radial loads, tab sis thaum lub radial clearance ntawm cov kabmob yog nce, nws muaj cov yam ntxwv ntawm angular hu pob bearings thiab tuaj yeem dais ua ke radial thiab axial loads; Nws tsis tsim nyog siv cov pob thrust ntawm kev kub ceev. Bearings kuj tseem siv tau los tiv thaiv cov axial ntshiab. Piv nrog rau lwm hom bearings nrog tib yam specifications thiab qhov ntev raws li qhov sib sib zog nqus groove pob bearings, hom kabmob no muaj qhov zoo ntawm kev sib txhuam me me coefficient thiab siab txwv ceev, thiab qhov tsis zoo yog tias nws tsis tiv taus qhov cuam tshuam thiab tsis haum rau nqa hnyav loads.
Tom qab qhov sib sib zog nqus groove pob bearing yog mounted rau ntawm ncej, nyob rau hauv lub axial clearance ntau yam ntawm cov kabmob, radial haum ntawm ncej los yog lub tsev nyob rau hauv ob txoj kev yuav raug txwv. Nyob rau hauv cov kev taw qhia radial, cov kabmob thiab cov ncej tau txais kev cuam tshuam zoo, thiab cov kabmob thiab qhov kawg npog cov kabmob chamber lossis plhaub tau txais kev cuam tshuam me me. Lub hom phiaj tseem ceeb ntawm kev xaiv hom kev haum no yog los xyuas kom meej tias kev ua haujlwm tshem tawm ntawm cov kabmob yog xoom lossis me ntsis thaum lub sijhawm ua haujlwm ntawm lub cev muaj zog. Tsis zoo, yog li kev khiav haujlwm ntawm cov kabmob zoo dua. Nyob rau hauv cov kev taw qhia axial, axial haum ntawm qhov chaw cov kabmob thiab cov khoom sib txuas yuav tsum tau txiav txim siab ua ke nrog rau cov xwm txheej tshwj xeeb ntawm cov kabmob ntab kawg. Lub nplhaib puab ntawm cov kabmob yog txwv los ntawm cov kabmob txwv cov kauj ruam (lub xub pwg nyom) ntawm tus ncej thiab cov kabmob tuav lub nplhaib, thiab lub nplhaib sab nraud ntawm cov kabmob yog tswj los ntawm kev ua siab ntev ntawm cov kabmob thiab cov kabmob chamber, qhov siab ntawm sab hauv. thiab sab nrauv ntawm cov kabmob thiab qhov ntev ntawm cov kabmob chamber.
Lub ntab kawg ntawm lub cev muaj zog kuj hu ua qhov kawg dawb, uas yog txheeb ze rau qhov kawg ruaj; Feem ntau, qhov kawg ntab yog xaiv ntawm qhov tsis tsav tsheb kawg, tab sis qhov kev xav tau ntawm lub cev muaj zog yog qhov siab, thiab qhov kev xav tau ntawm axial sib txuam nrog cov khoom siv thauj khoom tsis siab heev Qhov no, qhov kawg ntab yuav raug xaiv ntawm tus tsav. kawg.
Thaum lub cev muaj zog txhawb nqa lub cev yog ob lub fulcrum thiab ob chav kabmob qauv, thaum lub radial load yuav tsum yog loj, tus tsav kawg kuj yog siv raws li lub floating kawg, tshwj xeeb tshaj yog rau low-voltage high-power thiab high-voltage motors, lub cylindrical roller bearing ntawm qhov kawg ntab tuaj yeem ua tau raws li qhov xav tau ntawm cov khoom hnyav hnyav.
Cov menyuam thiab kev sib tw ntawm cylindrical roller bearing yog nyob rau hauv kab sib cuag lossis trimmed kab sib cuag, thiab radial bearing muaj peev xwm loj, uas yog qhov tsim nyog rau cov kabmob hnyav thiab cuam tshuam. Cov kabmob no muaj qhov sib txhuam me me thiab tsim nyog rau kev ua haujlwm nrog kev kub ceev thiab txwv ceev ze rau qhov sib sib zog nqus groove pob bearings. N-hom thiab NU-hom cylindrical roller bearings, uas feem ntau siv hauv cov motors, tuaj yeem txav axially nruab nrab ntawm cov kabmob sab hauv thiab sab nraud ntawm cov kabmob, uas tuaj yeem hloov kho rau cov kev hloov pauv ntawm tus txheeb ze ntawm tus ncej thiab lub plhaub los ntawm thermal expansion. los yog teeb meem kev teeb tsa, thiab tuaj yeem siv los ua kev txhawb nqa dawb kawg. Txawm li cas los xij, cov kabmob muaj kev ua haujlwm siab rau cov ncej lossis cov kabmob chamber qhov, thiab cov txheeb ze deflection ntawm lub nplhaib puab thiab sab nraud tom qab cov kabmob raug teeb tsa yuav tsum tau tswj nruj me ntsis kom tsis txhob muaj kev sib cuag nrog kev ntxhov siab.
Piv nrog rau qhov kawg ntawm cov kabmob, txhawm rau ua kom tau raws li qhov xav tau ntawm axial txav ntawm lub rotor thaum lub sijhawm ua haujlwm ntawm lub cev muaj zog, axial clearance xav tau ntawm lub nplhaib sab nraud ntawm cov kabmob thiab sab hauv thiab sab nrauv ntawm cov kabmob sib txawv raws li qhov txawv bearing xaiv.
(1) Thaum qhov kawg ntab tau txais cov kabmob uas sib cais sab hauv thiab sab nraud, rau lub cev muaj zog nrog ob lub qauv, qhov kawg ruaj yog xaiv ntawm qhov tsis tsav tsheb kawg; Lub nplhaib sab nraud ntawm qhov kawg ntawm qhov kawg thiab qhov ntab kawg cov kabmob thiab cov npog sab hauv thiab sab nrauv ntawm cov kabmob txais yuav tsis muaj axial clearance. Koom tes.
(2) Thaum qhov kawg ntab tau txais cov kabmob uas tsis sib xws, uas yog, ob qhov kawg ntawm cov motors me me thiab nruab nrab yog cov qauv sib xyaw ua ke. Raws li kev cuam tshuam ntawm kev txhim kho qhov tseeb ntawm cov cuab yeej rub tawm, kev tsav tsheb kawg yog siv los ua qhov kawg, thiab cov kabmob ntab kawg yog siv. Lub nplhaib yuav tsum raug txwv, thiab muaj qhov sib txawv axial ntawm lub nplhaib sab nrauv thiab sab hauv thiab sab nrauv ntawm cov kabmob; Nyob rau tib lub sijhawm, txhawm rau kom ntseeg tau tias cov kev sib txuam ntawm lub cev muaj zog ntawm lub cev muaj zog thiab cov kabmob sib koom ua ke tsis yooj yim ua kom nruj.
Qhov tseeb bearing configuration yuav tsum phim cov kev khiav hauj lwm ntawm lub cev muaj zog, nrog rau tej yam tsis xws li clearance, tshav kub tsis kam, thiab raug nyob rau hauv cov kev xaiv ntawm lub cev muaj zog bearings, nrog rau cov radial txuam kev sib raug zoo ntawm cov kabmob thiab cov kabmob chamber.
